Illusion is a combined effect on the mind and body.
 Holograms and stereogram use the stereo property of light to create
special effects which would be completely visual.
Visual effects created by 3D holograms are the most astonishing ones.
They use the seven colors of the solar spectrum in order to create
effects which would be very effective. Effective use of these techniques
in creating special effects is only possible due to the multicolored
spectrum of sunlight. It is an optical illusion if we describe it in a
very lucid language. The holograms create special effects which show
multiple images at the same time. Multiple images at the same time would
undoubtedly create effects which would be startling. These holograms are
mostly used in advertising and product logos. Often holograms are
considered to be signs of a genuine product and hence we can see that
optical illusion is finding a new application altogether. It is used in
product identification since counterfeit products cannot reproduce the
holographic effects.
3D illusions are very commonly in the form of pattern which would baffle
your eye if you stare at them continuously. The constant gaze would
generate special effects and one might see another figure inside the
pattern. This is totally uncharacteristic of the pattern shown in the
figure. Various such patterns are available which would show signs of
illusions to the viewers and mostly they appear to be hidden figures.
Color changes are noticed at times but color changes are more common in
3D holography. The color changes are used as the tools for bringing
about the special effects. Special effects are not effective if they
cannot use the subtle movements of the eye, hence this is purely an
optical phenomenon.
Optical illusions can also be used for the purpose of relaxation;
relaxation is very necessary in day to day life and any hectic schedule
needs to be followed with relaxation. Hence it is important that people
find newer ways of relaxation. 3D effects and optical illusion games can
also be used for relaxation since this would create soothing effects in
the eyes of the viewers. There are certain areas of the brain which is
affected by such visual effects. All effects created in the eye are due
to the effect of the particular area of the brain. Playing with colors
and dots are part of human nature and this characteristic is more
physiologically influenced.
hosts have been a topic of discussion for ages but the general ghosts
seen here and there are just optical illusions which force us to believe
in these things. Our central nervous cannot process the present images
properly, hence the images from past liger in it. This gives rise to
effects like ghost sightings and all. These are optical illusions which
arise due to the combined effect of mind and the eyes. Whenever we see
things that resemble the images stored in our memory, we tend to create
fresh images which would be something like a ghost sighting or an alien
sighting. Halloweens are ghost like faces which are created with the
help of various types masks which resemble various ghosts like
characters from our imagination. . The color changes are used as the
tools for bringing about the special effects. Special effects are not
effective if they cannot use the subtle movements of the eye, hence this
is purely an optical phenomenon.Manipulations are the key to all sorts
of optical illusions and hence one should always look for manipulative
art to put optical illusions to the best use. Some are more common than
the others while some are very rare. Illusions are part and parcel of
our daily lives and hence we can never stay away from illusion! Illusion
is a combined effect of the mind and the body.
